I OCH, citizen of the United States, residing at New York,

in the county of New York and State of New York, have invented certainnew and useful Improvements in Bottle-Caps, of which the following is aspecification.

This'invention relates to bottle caps, and belongs to that class ofclosures for bottles in which the caps are secured by crimps orindentations forced into a groove extending exteriorly around the mouthof the bottle. The object of this invention is the production of a capprovided with means insuring adequate elasticity to enable the'cap to bereadily applied and removed, in the customary manner, the capsbeingsecured to the bottles by continuous crimps or indenta-- tions, asdistinguished from the usual series of separated indentations, givinga'continuview after ous contact with the groove around the mouth of thebottle, and notmiely a number of,individual points of contact as in theordinary closures. In this invention the crimps' have specialarrangement with re spect to the devices giving the cap the necessaryelasticity, and the operation of crimp ing each cap slightly distortsits shape, causing the particularly formed and disthe cap between thedevices mentioned as affording elasticity, to increasingly projectbeyond the surface of the neck of the bottle and to give a convenientand advantageous purchase forthe opener, as hereinafter more fullyexplained.

The construction and arrangement constituting this invention areillustrated in the accompanying drawings, of which- Figure 1 representsa side view before the cap is crimped. Fig. 2 is a similar side the caphas,been crimped.- Fig. 3 is atop plan view of 'the invention asillustrated in Fig. 1. Fig. 4 is a plan view from below of the inventionas shown in Fig. 1, and Fig. 5 is a plan view from below showin theinvention as set forth in Fig. 2.

.Fig. 6 1s a side view of the neck of a bottle to which this inventionhas been applied, and shows the increased projection of thedownwardly-curving edges between the de-.

vices forelasticity, bringing those edges within easy reach of theordinary opener.

The same reference letter refers to the same part throughout thedescription and drawings.

The cup-shaped body A of this invention for has formed on opposite sidesthereof the .two hollow, outwardly convex extensions B and C, verticallyarranged, which give the body A sufficient elasticity to permit itsbeing applied and removed from the mouth of a bottle. Between theextensions B and C,the lower edge portions of the body A are curved andextended slightly downwardly and outwardly with respect to the bottom ofthe extensions B and O, as shown in Figs. 1, 3 and 4. The curved edgesare designated by the letters D and d, and, the position of those edgesare shownin the Figs. 1, 3 and {1, before the body is secured to abottle. i

It will be noted in Figs. 2, 5 and 6, that the four crimps E, F,throughout their length, and that there is a ".line of contact with thebottle groove in.-

mouth of the bottle H in the usual manner. The continuous'crimps securethe cap to the bottle very strongly, and it will be observed, forexample, in Fig. 6,-that each crimp begins at the side of the extensionB and extends toward the middle of the wall of the body A between theextensions. During .the crimping operation, the body A isdistortedslightly, and the downwardly-extended .curved edges D and d are causedto project to a somewhat greater extent, as shown in Figs. 5 and 6, thanbefore the crimping operation. The edges'D and dare inthat way forcedwithinconvenient reach of the ordinary opener. Itmay be explained here,that theopener may be applied to the extensions B and C, in opening thebottle. But, it is found to be easier to dislodge the body, A from itsposition upon thebottle, by causing the opener to engage one of theprojecting edges D or (Z, apparently for the reason that the crimps aremore readily drawn from the groove of the bottle when the power isapplied to one of. the edges D and C.

Having now described this invention and explained the mode of itsoperation, what I claim is v 1. A bottle cap,comprising a cupped bodyportion having a vertical cylindrical wall and hollow outwardly-convexextensions of said wall arranged vertically and opposite each other oneon either side of saidbody Patented Sept. 3, 1912.

e, f, are continuous disk G shown within the body A of this invention,which is pressed down upon the and d midway between the extensions 3whereby the body is rendered elastic, the lower'partgof said Wallbetween the extensions being extended downwardly lower than ,theextensions, and the said wall between the extensions being tionsbeginning atthe sides of said extensions and extending toward each otherwhereby the portions .of the vertical wall .midway between the saidextensions are bulged out Wardly from their original positions.

2. A bottle cap,comprising a cupped body portion having a verticalcylindrical wall, the said wallhaving modified portions constructed andarranged opposite each other whereby the body is rendered elastic, and

v N Copjes of this patent may be obtained for five cents each, by

provided with indentathe said wall between said modified portions beingprovided with indentations for holding the cap upon a bottle, the saidindentations beginning at the sides of the said modified portions of thewall and extending toward each other whereby the'portions' of thevertical wall midway between the said modified portions of the wall arebulged outwardly from their original positions.

In testimony whereof I aflix my signature in presence of two witnesses.
